Takeaway
Halosulfuron-methyl 70% WG at 36 g/acre on moist soil controls nutsedge but must be applied 40 days before transplanting chilli.
Summary
- Tunga (nutsedge/Cyperus) propagates via underground tubers that survive years without water and regenerate even from cut fragments.
- Heavy nutsedge infestation can reduce chilli yields by 50–60% as it competes for nutrients with the crop.
- Halosulfuron-methyl 70% WG is a selective systemic post-emergence herbicide sold as Dhanuka Sempra, Bharat, Elaan, Head Shot and other brands.
- Dose: 36 g per acre mixed in 150 litres of water, sprayed on moist soil 15–30 days after weed emergence.
- It is not selective in chilli — apply 40 days before chilli planting in deep furrows on moist soil.
